The loyalities of consumer feature changing, indicating PVC-linoleums

The paper describes the main types of PVC linoleum, form the basis of their current range, including a combined linoleum on the underlying basis hеаt-voice-insulating subbase, roll-calenders three-layered linoleum without an underlying cause foam and linoleum with printed design, such as L-1.8, we analyze the mechanism of the effect of composite components PVC linoleum their consumer characteristics. The main methods of study include an assessment of indicators of PVC linoleum consumer properties, including tensile strength samples (σr) on the tensile testing machine, volumetric weight (the mv) (density) and personal contact layer PVC linoleum method of hydrostatic weighing. In the process, investigated changes in tensile strength, bulk density (density) personal and contact layers of samples of PVC linoleum depending on the percentage of polymer, fillers and plasticizers in the linoleum of different composition, the observed changes are justified from a theoretical point of view. The prospects of using performance indicators of quality in carrying out various kinds of examinations of goods from plastics in general and PVC linoleum in particular, the experimental results allow us to identify certain patterns of changes in indicators of consumer properties of linoleum, depending on the formulation of their production, which will contribute to the optimization of the research and forecasting of consumer properties of the finished product depends on the percentage of the constituent components. These laws, although some of them and can not give an unambiguous interpretation, generally characteristic of the materials in question and may even give some idea about some of the features of the polymer compositions. But the specificity of certain consumer properties of PVC materials for floors (for example, the stability of the linear dimensions, the absolute tensile strength) determines the binding link the results obtained with the features of the technological process of the studied species linoleum.
